Sister Wife

Best friend that is so close to you, she is like another wife your husband married. Husband may mistake her for his wife when she and wife are in the front seat of the car and said husband is in the back seat. Inflection and speech begin to mirror each other. Your kids may favor her over their own parents, and she treats them like they are her own! Not to be confused with sister from another mister.

My husband does not know who he is going to see first when he gets home, myself or my sister wife!

Sister wife

A female lover of a woman who is already married their partner. And the partner is totally cool with it and gets in on the action every once in a while, but the female lover is purely in the relationship romanticly with the woman married to the partner. In some instances the female lover is romanticly involved with the married partner as well as the original female. This could also work with two male partners and the female lover is included in the same way as discribed above.

My husband joined in while my sister wife and I were making love.

Fake Sister

A term often used by males to describe their relationship with a girl who is not their girlfriend, but a close friend. This term does not apply to blood-relatives.

This classification boasts qualities typically seen in brother/sister relationships (e.g., mildly derogatory dialogue, occasional use of derogatory hand gestures, random story telling and re-telling, matchmaking, inside jokes, mutual-aid and support related to interference by outside parties, and the occasional transfer of funds with no repayment plan).

Person 1: "Did you see how fat so-in-so has gotten?"
Person 2: "Hey, watch your face, that's my fake sister you're talking about."

Person 1: "So-in-so said you loaned her $200"
Person 2: "Yeah, it's ok. She's my fake sister. I'll hit her up for $400 next time."
